Add a new iocage API call to deactivate pools.

REST Request:
-------------------------------
PUT /sysadm/iocage
{
   "action" : "deactivatepool",
   "pool" : "tank"
}

REST Response:
-------------------------------
{
    "args": {
        "deactivatepool": {
            "success": "pool tank deactivated."
        }
    }
}

WebSocket Request:
-------------------------------
{
   "id" : "fooid",
   "name" : "iocage",
   "args" : {
      "pool" : "tank",
      "action" : "deactivatepool"
   },
   "namespace" : "sysadm"
}

WebSocket Response:
-------------------------------
{
  "args": {
    "deactivatepool": {
      "success": "pool tank deactivated."
    }
  },
  "id": "fooid",
  "name": "response",
  "namespace": "sysadm"
}

Also added some error control to the activate API call.
